Alright, I understand. Well there would be new keys soon so you can try then! Please try to follow the suggestions posted in the first post for that one! You can check on the main site when the keys are available again
EDIT:
We found a new item that may solve the problem:
1) When you login you get a page saying "redirecting you" and it has a link to continue, or if you wait it'll do a javascript thing
2) js fires, opens the URL (runs the script). while it's loading you click on the link... open the URL, run the script again - get the "already got key" page
This means:
If you have the error and you want the error to stop: please make sure you DO NOT click the link, when the event redirects you!
If anyone who usually has the error can confirm this, I'd be delighted!
